Product details
Overview
RI-TRP-IR2B-01 from Texas Instruments is a 32-mm hermetically sealed glass passive LF RFID transponder operating at 134.2 kHz, compliant with ISO 11784/11785, featuring MPT 1360-bit memory (17 R/W pages), HDX half-duplex communication, and batteryless operation powered by reader field. It delivers stable read/write performance in access control and asset tracking.
For engineers reviewing the RI-TRP-IR2B-01 datasheet, RI-TRP-IR2B-01 application, RI-TRP-IR2B-01 equivalent, or RI-TRP-IR2B-01 physical dimensions, this page provides verified technical context, pinout-free package details, real-world use cases, and validated alternative transponders for ISO-compliant LF RFID system design.
Technical Context
The RI-TRP-IR2B-01 implements TI's patented HDX (half-duplex) modulation scheme using FSK at 134.2 kHz and 123.2 kHz, enabling robust bidirectional communication without an onboard power source. Its resonant LC circuit-comprising integrated antenna inductance and tuning capacitor-is factory-optimized for consistent coupling across varying reader antenna configurations.
It supports selective addressing and secured programming via multipage architecture, with full functional and parametric testing performed pre-shipment. The glass encapsulation ensures IP68-level environmental protection, immunity to nonmetallic interference, and stable performance from –25°C to +85°C ambient.

Equivalent & Alternatives
The following parts are listed as comparable options for similar passive LF RFID transponder applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RI-TRP-WR2B-01 | Same 32-mm glass form factor and ISO 11784/11785 compliance; uses WDP protocol instead of MPT; 1024-bit memory (16 R/W pages). | Optimized for write-once/read-many (WORM) use cases; lacks selective page erase capability of RI-TRP-IR2B-01. | Select when data immutability is required and page-level reprogramming is unnecessary. |
| RI-TRP-DR2B-40 | Identical electrical specs, packaging, and HDX operation; differs only in part marking and tape-and-reel packaging variant (2000 pcs/reel vs. 01 suffix). | No functional difference; both meet same production qualification and environmental testing standards. | Select based on procurement volume and logistics preference-no design or performance trade-offs. |
Compared with RI-TRP-WR2B-01 and RI-TRP-DR2B-40, the RI-TRP-IR2B-01 uniquely balances multipage programmability, 1360-bit capacity, and field-proven HDX reliability-making it optimal for applications requiring frequent, secure, and selective data updates in harsh environments.

FAQ
What is the operating frequency of the RI-TRP-IR2B-01?
The RI-TRP-IR2B-01 operates at a precise 134.2 kHz resonance frequency, fully compliant with ISO 11784 and ISO 11785 standards for low-frequency RFID systems. This frequency enables reliable inductive coupling with standard reader antennas and ensures global regulatory acceptance in animal identification, access control, and logistics applications.
Is the RI-TRP-IR2B-01 compatible with ISO 11784/11785 readers?
Yes, the RI-TRP-IR2B-01 is explicitly designed and tested for full compliance with ISO 11784 (coding structure) and ISO 11785 (air interface protocol). It responds to standard HDX interrogation signals and supports the mandated 134.2 kHz carrier, making it interoperable with certified readers used in veterinary, transportation, and security systems worldwide.
Does the RI-TRP-IR2B-01 require a battery?
No, the RI-TRP-IR2B-01 is a fully passive transponder that draws all operating power from the electromagnetic field generated by the reader antenna. Its integrated LC resonator converts RF energy into DC voltage to power the internal circuitry-eliminating batteries, maintenance, and end-of-life disposal concerns.
What is the memory configuration of the RI-TRP-IR2B-01?
The RI-TRP-IR2B-01 features 1360 bits of user-programmable memory organized into 17 read/write pages. This architecture supports selective addressing and secured programming, allowing partial updates without erasing the entire memory-ideal for dynamic asset tracking and event logging applications.
Can the RI-TRP-IR2B-01 be embedded in metal environments?
No-the RI-TRP-IR2B-01 is highly sensitive to metallic materials due to eddy current losses that detune its 134.2 kHz resonant circuit. It is specifically rated for use behind or within nonmetallic substances (e.g., plastic, wood, concrete). For metal-mount applications, TI offers ferrite-backed variants such as the RI-TRP-MR2B series.
